Title: Electric control device of internal combustion engine
Inventor: UCHINAMI MASANOBU
IPC: F02D45/00
Filed: 1991-08-03
Abstract: PURPOSE:To make fault judgement of an EGR control device accurately by means of an electronic control device of a cheap construction. CONSTITUTION:An electromagnetic valve is turned on (EGR, not introduced) or off (EGR introduced) depending on whether the operating condition of an internal combustion engine is in EGR control zone or not (steps 103 and 106). When the conditions for fault judgment are completely arranged, an NOX amount in exhaust gas is read as voltage signal VOFF (EGR not operated) or VON (EGR operated) (steps 105 and 108). Then the VOFF is compared with a specific value V2 (steps 112) or the VON is compared with a specific value V1 (step 109) and, if the VOFF<=V2 or VON>=V1, an EGR control device is judged faulty and the fault is remedied (S110). Also, fault judgement can be carried out by comparing the output of an exhaust gas temperature sensor during the operation of the EGR with that during non-operation thereof.

Title: Semiconductor delay circuit
Inventor: SHIBATA SHINTARO
IPC: H03H11/26
Filed: 1993-07-12
Abstract: PURPOSE:To hold the duty of a signal even when unit circuits which are not uniform in rise and fall delay time by arranging and connecting an inverter for signal polarity inversion between unit circuits in the semiconductor delay circuit of unit circuit array constitution. CONSTITUTION:The inverter 1 which inverts signal polarity is arranged and connected between unit circuits DU(k) and DU(k+1). Then when an input signal VIN varies from as L level to an H level, (k) unit circuits DU(k) (k=1, 2...k) in the front stage of the unit circuit array generate a rise delay time DELTATr respectively. The remaining (k) unit circuits DU(k) (k=k+1, k+2...2k) in the rear stage, on the other hand, generate a fall delay time DELTATf through the inversion of the inverter 1. Then when the input signal varies from the H level to the L level, on the other hand, the reverse results are obtained the rise and fall delay times TRD and TRF of the whole delay circuit are approximated by equations and II. Judging from both the equations, the delay times TRD and TRF become equal even when delay times per circuit DU(k) are DELTATrnot equal to DELTATf, so the duty of the signal at the input and output is held at all times.

IPC: G11C11/409
Filed: 1993-08-06
Abstract: PURPOSE:To obtain a high integrated DRAM to be operated with a single external power source, having a wide voltage margin. CONSTITUTION:A word driver WD is operated by voltages VWH and VWL obtained by boosting a high level VDH and a low level VDL of data lines Dt and Db in a memory array MCA by boosting circuits GVWH and GVML respectively, and a voltage amplitude of a word line W is formed from the VWL to the VWH. By this method, without increasing a subthreshold current of a MOS transistor in a memory cell MC, a threshold voltage can be diminished. Thus, a wider voltage margin can be obtained by using a MOS transistor of the same breakdown strength as the conventional one.
